The boiling point of FAT 45'176/A (H-form) was calculated to be about 692 °C using Meissner's method.

Conclusions:
The vapour pressure of FAT 45176/A was 5.75E-20 Pa.
Executive summary:

The vapour pressure study was carried out as per OECD 104 and EU A.4 guideline using calculation method. Based on the calculation the vapour pressure of FAT 45176/A was 5.75 x 10-20 Pa at 25 °C based on the boiling point calculated and using the Modified Watson Correlation.
